Looping with the Regex

If I have the following text file.

$string = 
'1)	The most important feature of spiral model is: requirement analysis. Risk management. quality management. configuration management	2)	The worst type of coupling is: Data coupling. control coupling. stamp coupling. content coupling 3)	One of the fault base testing techniques is: Unit testing. beta testing. Stress testing. mutation testing 4)	A fault simulation testing technique is: Mutation testing. Stress testing. Black box testing. White box testing 5)	RS is also known as specification of: White box testing. Stress testing. Integrated testing. Black box testing 6)	Which of these terms is a level name in the Capability Maturity Model?: Ad hoc. Repeatable. Reusable. Organized 7)	FP-based estimation techniques require problem decomposition based on?: Information domain values. project schedule. software functions. process activities 	What types of models are created during software requirements analysis?: Functional and behavioral. Algorithmic and data structure. Architectural and structural. Usability and reliability 9)	Which of the following is not an attribute of software engineering: Efficiency. Scalability. Dependability. Usability

With the Regex below that I have, How do I loop through the regex to get my code display one question at a time. When I submit, I proceed to the next one. Thank you.

Try,

$openFile = fopen("questionandanswers.txt", "r") or exit ("unable to open the text file");

$string = fread($openFile, filesize("questionandanswers.txt"));

// match all characters sequence
preg_match_all('/[a-zA-Z.:?,-\s]+(?=\d\))/', $string, $parts);

// reindex the array starting to 1
$iOne = array_combine(range(1, count($parts[0], COUNT_RECURSIVE)), array_values($parts[0]));

//echo '<pre>'.print_r($iOne, true).'</pre>';

// count all re-index keys of that array 
$count = count($iOne);

// loop through array keys and display the results
for($i=1;$i<$count;$i++){
    
 echo $i.')'.$iOne[$i]."<br />";
 
}

Results:

1) The most important feature of spiral model is: requirement analysis. Risk management. quality management. configuration managemen
2) The worst type of coupling is: Data coupling. control coupling. stamp coupling. content coupling
3) One of the fault base testing techniques is: Unit testing. beta testing. Stress testing. mutation testing
4) A fault simulation testing technique is: Mutation testing. Stress testing. Black box testing. White box testing
5) RS is also known as specification of: White box testing. Stress testing. Integrated testing. Black box testing
6) Which of these terms is a level name in the Capability Maturity Model?: Ad hoc. Repeatable. Reusable. Organized
7) FP-based estimation techniques require problem decomposition based on?: Information domain values. project schedule. software functions. process activities

Thank you for the contribution jazzman1, What I am trying to do is to read the text file line by line. But I can only proceed to the next line only after I have answered a question of the first line, progressively upto the last one. Thank you.

Get all radio buttons into an array and then switch the answers and case radio buttons in your processor.php file.

Something like: (be careful with radio buttons, they contain empty strings, just trim them)

echo '<pre>'.print_r($_POST['selected_answers'][0], true).'</pre>';

switch($_POST['selected_answers'][0]) {
    
        case " requirement analysis":
            $value = '<pre>'.print_r($_POST['selected_answers'][0], true).'</pre>';
            break;
        case "Risk management":
            $value = '<pre>'.print_r($_POST['selected_answers'][0], true).'</pre>';
            break;
        case "quality management":
            $value = '<pre>'.print_r($_POST['selected_answers'][0], true).'</pre>';
            break;
        default:
            $value = "No radio has been selected for selected_answers";
    }
    
    echo $value;

A lot of coding there, Thanks it also gives me an insight of what to do in my processor.php Thanks for that. But actually its not what I want to accomplish. When I use the above codes that I had before, I display the questions as a block in the browser. But now using the function

fget () and not fread ()

I want to loop my the questions one at a time and each can be submitted in each session as I progress through all of them up to the last one. Sounds a bit complicated by thats what actually I am trying to achieve. But I am really thankful and appreciate the efforts you are making jazzman1 to assist me crack this jazzman1.
